An industrial, duo-triode (virtually the same specs as the E180CC or 7062)

An industrial, computer rated dual triode, virtually the same specs as the E180CC or 7062. Made in the USA. This tube is also like a 12AV7 and will work wonders in any 12AT7 spot, and may be just the ticket if you want to boost the gain of a 12AU7 circuit. Very hard to find, but with a 10,000 hour heater rating you may never need a replacement. Discussion groups rate this type very highly for use in headphone amps.
